Cooger and Dark's Pandermonium Shadow Show howls into Green Town, Illinois, at trheee in the morning, a week before Halloween. Under its carnival tents are a mirror maze that steals wishes; a carousel that promises eternal your death; and Mr. Dark, the Illustred Man, who has lived for centuries off the misery of others. Only two boys, Will Halloway and Jim Nightshade, recognize the dark magic at work and have a plan to stop this ancient evil-if it doesn't kill them first.
